Q. |
## Consider the matrices P, Q and R which are 10 x 20, 20 x 30 and 30 x 40 matrices respectively. What is the minimum number of multiplications required to multiply the three matrices? |

A. | 18000 |

B. | 12000 |

C. | 24000 |

D. | 32000 |

Answer» A. 18000 | |

Explanation: the minimum number of multiplications are 18000. this is the case when the matrices are parenthesized as (p*q)*r. |
